95 Corsica Check Engine Light

I got my dad's new(?) Corsica all buttoned up for him & sent it home with him a few weeks back. But now dad reported that the CHECK ENGINE light comes on during a long trip (after about an hour drive). Around town, the light stays off. When the light does come on, dad pulls over & shuts off the engine, waits a minute, restarts it, it restarts promptly & the light goes out like normal. It runs fine when the check engine light is on. Car has 177K miles on it (original engine 3.1 liter V6) and has very little oil consumption (about a quart low after 4k miles). I will scan for the codes this weekend, but was wondering in advance if there is anything that is usually the culprit for this kind of intermittant problem, like a highly suspect & high percentage failure rate component. I also understand that if multiple codes are present, it could be a single culprit - or could also still be MULTIPLE culprits. I have only performed ECM diags a handful of times, so any guidance would be a big help & much appreciated.

Thanks!

Marty
